Display

The touchscreen is a single touch resistive touchscreen. It is implemented as a PET film laminated to the front of an unpolished coverglass, which is then attached with adhesive (but not optically laminated) to the front of the LCD module.

There is no internal microphone. There is a single internal speaker.

Connectivity

A 100baseT connection is provided via an RJ-45 jack. No wireless networking is included.

Location/Movement

No location or movement sensing is provided.

Ports

Two USB type A ports, listed as 2.0 in the specs. The AM1808 only supports a single USB 2.0 port, so one of these is a USB 1.1 port.

The Sitara SoC supports OTG, although the Bharat tablet doesn't.

One RJ-45 for 100baseT

One microSD card, only accessible internally.

One full size SD card, externally accessible (no cover)

One 1/8" stereo phono jack for Headphone

One 1/8" stereo phono jack for Microphone

Power

The Bharat Tablet has a 14.8Wh Li-Ion polymer battery (4Ah @ 3.7V nominal). It is notable that the battery compartment is easily accessible (one screw), and the battery may be replaced without disassembling the unit. The battery size requires is clearly imprinted in the plastic.

The battery is not a smart battery (only a two wire connection), and there is no battery "gas gauge" on the motherboard.

Breakdown

The tablet opens quite easily (just 10 screws, no adhesives), breaking down into a bottom half containing the single PCB and the battery, a bezel, and the sandwich of touchscreen and display.

The screws are all self-tapping, going directly into plastic bosses.
